Germany’s 2027 E-Invoicing Deadline: Who Is in Scope? 

A practical guide to the €800,000 threshold, affected transactions, exemptions, and preparation steps 

The short answer 

Germany’s e-invoicing transition is phased. From 1 January 2027, businesses whose total turnover in the previous calendar year exceeded €800,000 will generally have to issue structured electronic invoices for in-scope domestic business-to-business (B2B) transactions. Businesses below that threshold can generally continue using certain alternative invoice formats during 2027, subject to the statutory transition rules. From 1 January 2028, the issuing obligation is scheduled to extend to domestic businesses more broadly, with specific exceptions. 

The important distinction is that the 2027 date is not the first time German businesses must deal with e-invoices. Since 1 January 2025, businesses have generally needed to be able to receive structured e-invoices for relevant domestic B2B transactions. The 2027 milestone mainly changes who must issue them. 

What counts as an e-invoice? 

Under Germany’s VAT rules, an e-invoice (E-Rechnung) is not simply any invoice sent electronically. It must be issued, transmitted, and received in a structured electronic format that enables electronic processing and complies with the applicable legal requirements. A conventional PDF sent by email is generally treated as a different type of invoice, not a structured e-invoice, unless it is part of a compliant structured format. 

Common formats in the German market include XRechnung and ZUGFeRD, provided the version and implementation meet the applicable requirements. Companies should validate their chosen format and workflow against the technical and legal requirements rather than assuming that every PDF or accounting-system export qualifies. 

Who is in scope from 1 January 2027? 

The key group is businesses making in-scope domestic B2B supplies where the issuing business’s relevant total turnover in the preceding calendar year was more than €800,000. For the 2027 transition, this means businesses generally assess their 2026 turnover against the €800,000 threshold. 

Business / situation 2027 position Practical implication 
Relevant 2026 turnover above €800,000 Generally required to issue structured e-invoices for in-scope domestic B2B transactions from 1 January 2027. Review invoice software, data quality, validation, delivery and archiving. 
Relevant 2026 turnover of €800,000 or less May generally use transitional alternatives for qualifying 2027 transactions, subject to the statutory rules and recipient-consent requirements for non-structured electronic formats. Use the transition year to implement and test compliant e-invoicing. 
Business receiving domestic B2B invoices Must generally be able to receive e-invoices from 1 January 2025, regardless of size. Set up a workable receiving channel, review process and compliant storage. 
Domestic B2C transactions Generally outside this domestic B2B issuing mandate. Check the transaction type and any separate sector-specific obligations. 
Cross-border transactions Not automatically covered by this specific domestic B2B mandate. Assess the applicable country rules and any other German VAT requirements. 

How the €800,000 threshold works 

The threshold is based on the issuing business’s relevant total turnover in the previous calendar year under the applicable German VAT rules. It is not simply a test of the value of one invoice, one customer account, or the turnover of a particular product line. Businesses should confirm the statutory turnover calculation with their tax adviser, especially where they have mixed activities, multiple establishments, special VAT treatment, or complex corporate structures. 

For invoices issued in 2027, businesses should therefore review the relevant 2026 figures early. If turnover is close to the threshold, document the calculation and the assumptions used. Do not treat the €800,000 threshold as a permanent exemption: the broader issuing requirement is scheduled to apply from 2028, subject to exceptions such as the rules for small businesses. 

Which transactions and businesses may be excluded? 

The mandate is focused on specified domestic B2B transactions, and the legislation provides exceptions. Depending on the facts, these can include certain VAT-exempt supplies, invoices for small amounts up to €250, and passenger transport tickets. Special rules also apply to small businesses under the German small-business VAT regime (Kleinunternehmerregelung). 

Do not assume that an entire business is exempt because one category of invoice is excluded. A company may issue different types of invoices, and each transaction should be assessed against the relevant rule. Public-sector transactions can also be subject to separate e-invoicing requirements, so businesses dealing with public authorities should review those obligations independently. 

Can businesses continue using PDFs or EDI in 2027? 

The transition rules matter. During 2025 and 2026, businesses can generally use paper invoices or, with the recipient’s consent, other electronic formats such as a conventional PDF instead of a structured e-invoice for qualifying transactions. For 2027, the transition is extended for issuers whose relevant previous-year turnover does not exceed €800,000. A separate transitional provision allows certain EDI procedures that do not otherwise meet the structured e-invoice requirements to continue through 31 December 2027. 

These are transitional permissions, not a reason to postpone planning. The exact treatment depends on the transaction, format, recipient consent where required, and whether the invoice satisfies the statutory conditions. Businesses should check their arrangements against current German Ministry of Finance guidance. 

What should businesses do before the deadline? 

  1. Map your transactions Identify domestic B2B supplies, B2C sales, cross-border transactions, public-sector invoices, and any special or exempt categories. 
  1. Confirm your threshold position Review the relevant 2026 turnover calculation and record whether the €800,000 threshold is exceeded. 
  1. Check software and formats Ask your accounting or ERP provider whether it can create and receive compliant structured invoices, including the relevant XRechnung or ZUGFeRD implementation where appropriate. 
  1. Validate invoice data Check customer and supplier identifiers, tax information, line-item data, totals, and other required fields. Introduce technical validation before invoices are sent. 
  1. Design receiving and exception workflows Decide who monitors incoming invoices, how errors are handled, and how invoices are routed to accounts payable and approvers. 
  1. Review archiving and access Ensure the structured invoice data is retained in accordance with applicable record-keeping rules and can be retrieved in a readable, auditable form. 
  1. Test with trading partners Run end-to-end tests for sending, receiving, rejection handling, corrections, and credit notes before the deadline. 
  1. Train finance and operations teams Give staff clear instructions on valid formats, common errors, escalation routes, and the difference between a structured e-invoice and a PDF. 

Why early preparation matters 

E-invoicing is not only a tax-format change. It can affect accounts payable and receivable, ERP configuration, master data, approval workflows, integrations with customers and suppliers, audit trails, and how teams resolve rejected invoices. Starting early gives businesses time to test their systems and resolve data or process gaps before invoice volumes rise or transition options expire. 

For international groups and suppliers serving German customers, the practical first step is to identify which legal entity issues each invoice and where the underlying transaction takes place. A group-wide policy can help, but it should not replace a transaction-level assessment of German requirements.
